The poles that provide electricity for trains are at risk of collapse, even as power substations succumb to floodwaters. “If one of the segments of track shuts down, it will shut down this segment of the NEC,” warned members of Amtrak’s planning staff. “There is not an alternate route that can be used as a detour.”
